Led package for increasing illumination and spotlighting

Abstract

A LED package for increasing illumination and spotlighting includes a base, a LED chip and an enclosure. The enclosure is made of an optically transparent silicone for increasing the illuminative range. In addition, a light-guide curved surface can be placed on the inner side of the enclosure for spotlighting the emitting light in a certain orientation.

1 . A LED package for increasing illumination and spotlighting comprising:
 a base, a LED chip and an enclosure being made of an optically transparent silicone;   wherein the LED chip is placed on the base and is electrically connecting to the base, the LED chip enclosed by the enclosure on the base, a filling material poured into the enclosure and solidified to form a filling lens such that the LED chip is packaged in the filling lens.   
     
     
         2 . A LED package for increasing illumination and spotlighting comprising:
 a base, a LED chip and an enclosure;   wherein the LED chip is placed on the base and is electrically connecting to the base, the LED chip enclosed by the enclosure on the base, a filling material poured into the enclosure and solidified to form a filling lens such that the LED chip is packaged in the filling lens, an inner side of the enclosure having a light-guide curved surface deposited thereon, the light-guide curved surface having a sub layer coated thereon for reflecting the emitting light from the LED chip.   
     
     
         3 . The LED package for increasing illumination and spotlighting as claimed in  claim 2 , wherein the sub layer is made from an optical micro structure which reflects the light.
